because when the room is tight, in order to reduce noshow and ensure the normal check-in of the guests, credit card guarantee is needed. If the guests fail to check in as scheduled, Ctrip will deduct all or part of the room fee. Generally, the situations that need to provide guarantee are:

a. tourist peak season or hot spots;

B. hotels during exhibitions or national holidays;

C. the retention time exceeds the hotel limit, etc.

D. According to the practice of overseas hotels, in order to ensure the normal check-in of guests, all hotels need to provide credit card guarantee. If the guests fail to check in as scheduled, all or part of the room fee will be deducted according to the reservation terms.

if you still have questions, I suggest you call our customer service, and someone will help you.
